Another Yamaraja? How many are there? Well, anyways...Seeing as the thing's fire-based, you'll want Yuri to fuse into Man Dragon and use Flash Flood every turn. Zhuzhen's on healing duty, of course, and Margarete can dish out some decent damage with her physical attack, being water-based and all. He casts a random buff at the beginning of the battle, but it shouldn't affect anything seriously. This guy is tough, but he doesn't seem to last as long as the other Yamarajas. If Yamaraja Stone uses Wall of Resistance then just dish out physcial attacks till it wears off.
